Senior Backend Engineer - Shape the Architecture, Build for the Future

About the role

We're looking for an experienced senior backend engineer to join our Checkout team. This is a great opportunity for someone who enjoys working on complex, business-critical systems and takes pride in building software that is reliable, maintainable, and built to last.

You'll work closely with your team and stakeholders in both delivery and discovery — helping shape technical direction, contributing to sound architectural decisions, and ensuring steady, predictable progress. We value engineers who are comfortable taking ownership, questioning the status quo, and suggesting improvements when they see them.

How you will make an impact

• Contribute hands-on to the development and maintenance of complex, business-critical backend systems.

• Drive our testing strategy forward and play a key role in moving the team towards continuous delivery and deployment.

• Drive architectural discussions and help evolve our service architecture to support scalability and long-term sustainability.

• Foster a culture of continuous improvement and contribute to the technical growth of the team.

• Communicate technical plans, trade-offs, and solutions clearly to both technical and non-technical stakeholders.

Who we think you are

• You have strong experience in backend development using Java and/or Kotlin, and feel confident working in modern backend architectures.

• You have solid experience working with databases, particularly document stores such as MongoDB or similar.

• You have a solid understanding of system design and distributed architectures, and can design scalable, reliable services.

• You have hands-on experience with testing strategies and a genuine interest in improving test coverage, test automation, and CI/CD pipelines.

• You take pride in writing clean, maintainable code and understand the importance of quality, performance, and security.

• You communicate clearly and effectively in English, both verbally and in writing.
